How to Solve Number Series Tutorials

The “number series” tutorials of PH Civil Service review contains tutorials on methods and strategies used in solving number series problems. As I have mentioned in the teaser of this tutorials, the term “series” is technically wrong: what you are solving are really sequences. Although they maybe similar to many of you, to mathematics majors, they are very different. In mathematics, series means sequence of sums. I will not go into details about this since this is irrelevant for the review. In this series of tutorials, mathematically, we will use the term “series” and “sequence” interchangeably.
